“The company snapped up four floors at 4 Copley Place for its new headquarters, which are down the street from the original office at 177 Huntington. (Some people still work out of the Huntington building, however, as well as an additional spot on Boylston Street.)…The reasoning behind the new, 120,000-square-foot location is obvious: More space for Wayfair’s seemingly ever-increasing staff. Around 900 people currently work for the home decor firm, with 20 to 25 newcomers being added each week.”
